Porsche 911 Turbo

From Porsche press: Like the two generations before it, the latest 911 Turbo Cabriolet shares its essential architecture with the latest Turbo Coupe, most critically, that car's 3.6-liter horizontally opposed six-cylinder engine, Porsche VarioCam Plus variable intake timing and lift, and twin variable-vane turbochargers.

The engine develops 480 bhp and 460 lb.-ft. of torque while meeting LEV-II emissions standards and being fuel efficient enough to not be penalized as a gas guzzler. The Turbo Coupe is available with the optional Sports Chrono Package Turbo with its overboost feature that allows bursts of an additional 44 lb.-ft. of torque as desired by the driver.

Driving through either a standard-equipment six-speed manual or optional five-speed Tiptronic S transmission, the engine's output is maximized at all four tires by electronically controlled all-wheel drive system, Porsche Traction Management (PTM).
